Hi guys I am at the point in the restoration of my 69 Camaro that I want to but a 4 speed. I don't want a 5 speed. What are your recommendations I have a chevy small block with about 410 hp street driven only, 3.73 gears. I have heard a lot about these new M22 super case transmissions are they all that are they as strong and dependable as everyone says? How loud is loud? that's a big concern. Can you talk to someone in the car? I think having it for resale value is good.

I have a buddy who will sell me his M20 for $500.00 but it needs a complete rebuild. What are your thoughts. I don't no if it needs a rebuild kit or gears, etc. So that could be pricey also.

The M22 can certainly handle the HP you are talking about with no problem whatsoever. You are wise to be wary of the used M20. You very well could spend a sizable chunk of change on it. On the other hand, if you have the chance to do a visual internal inspection look for any gear teeth missing. Also look at the synchro ring engagement cogs on the gears. If they are all rounded off I would pass on the trans. If it appears to be in pretty good shape it would be a fairly good buy and could be freshened up with a master rebuild kit for about $160.

I run a M 20 in my 40 ford ,also I run 3:55 Ford 9 inch posi , and a 383 stroker with 500 Hp and it works great, like you say the rock crusher is real noisy , I myself would recommend the M20 or 21 .I just had my M20 refreshed for $ 150.00 .
